RECIRCULATION CONTROL MOTOR TEST 

1. Disconnect the 7P connector from the recirculation control motor. 

2.  

Connect battery power to the No. 1 terminal of the recirculation control motor, and ground the No. 5 or 
No. 7 terminals; the recirculation control motor should run smoothly. To avoid damaging the 
recirculation control motor, do not reverse power and ground. Disconnect the No. 5 or No. 7 terminals 
from ground; the recirculation control motor should stop at Fresh (when the No. 7 terminal is 
disconnected) or Recirculate (when the No. 5 terminal is disconnected). Don't cycle the recirculation 
control motor for a long time. 

NOTE:

Incorrectly applying power and ground to the recirculation control motor 
will damage it. Follow the instructions carefully.

the linkage. After installation, make sure the motor runs smoothly.  

DUST & POLLEN FILTER REPLACEMENT 

The dust and pollen filter should be replaced every 30,000 miles (48,000 km) or 24 months whichever comes 
first. Replace the filter more often if the air flow is less than usual, or if the vehicle is driven in areas that have 
high concentrations of soot from industry or diesel powered vehicles. 

1. Open the glove box. Remove the damper from the glove box, then let the glove box hang down (see 

GLOVE BOX REMOVAL/INSTALLATION ).  

2. Remove the dust and pollen filter assembly from the evaporator.
